If you are as big and long-term a geek as me, you'll remember the debut in the mid/late 90's of babelfish.altavista.com - the world's first Internet translation service. I had hours of fun translating random chunks of English into French, Spanish, Italian, and German. Sometimes I even used it at the library to help people!
Over the years, AltaVista changed hands a couple of times, but BabelFish stayed free and even added languages. Fastforward to today, and say hello to Yahoo! Babel Fish[3], still free and now offering Simplified Chinese into Traditional Chinese, and Traditional Chinese into Simplified Chinese. You can even add Babel Fish to your Yahoo! Toolbar now.
Pretty neat! Read all about it on the Yahoo! Search blog[4].
